ASTM A671 Grade CB60 CL12 EFW PIPES Application
Steel, where the main alloying constituent is carbon, is called Carbon Steel or plain carbon steel. The American Iron and Steel Institute (AISI) defines carbon steel as: “Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60.”
This type of steel is applied in various industries and for critical engineering purposes. Other value-added products of carbon steel include LPG cylinders, corrosion-resistant steel, precision tubes and medium/high carbon grades, critical structural application steel, etc.
